Answer:
Area = 77.1
Step-by-step explanation:
The are of a right triangle is

our base and height are 6 for both triangles, so we shall find the area of one of the triangles...

multiply this by 2

Now find the area of the whole circle

our radius is 6, therefore:

Finally, subtract the area of the two triangles from the total are of the circle. The difference left over is our answer

The intervals refer to the x values where the function (graph) is increasing which means the y values are getting larger from left to right. Parantheses are used not brackets (parantheses means it doesn't include the value and brackets mean it does) so here the intervals would be
( negative infinity , -3)U( -3, 0 )
Given:
The figures of triangles and their mid segments.
To find:
The values of n.
Solution:
Mid-segment theorem: According to this theorem, mid segment of the triangle is a line segment that bisect the two sides of the triangle and parallel to third side, The measure of mid-segment is half of the parallel side.
9.
It is given that:
Length of mid-segment = 54
Length of parallel side = 3n
By using mid-segment theorem for the given triangle, we get



Divide both side by 3.


Hence, the value of n is equal to 36.
10.
It is given that:
Length of mid-segment = 4n+5
Length of parallel side = 74
By using mid-segment theorem for the given triangle, we get




Divide both side by 4.


Hence, the value of n is equal to 8.
